TOOL FOR TWISTING WIRE TIES.

APPLICATION FILED MAY 4, 1908.

Patented Jan. 5; 1909.

To all whom it concemi UNITED snares PATENT OFFICE.

i i i Be it known that I, J 01m P. CURRY, a citizen of the United States, residing at 62 West Eighty-ninth street, New York, county of New York, and State, of New York, have invented certain new "and useful Improvements in Tools for Twisting Wire Ties, fully descr1bed; andrepresented in the following specification and the accompanying draw- S; forming a part of the same.

. helqhject of this invention is to furnish amea "sf-tor securing upon the neck of a bag art ele a wire-tie having eyes or When such a or other article, the portions of the wire adjacent to the end eyes may be twisted together leaving the eyes spread apart in such position that they may be readily used in antw sting the tie o op n the b g. Such a wire-tie is valueless without such a tool as I have invented vtot-wist the ends of the wire and leave the eyes suitably separated to use for untwisting. The application of such a Wire-tie to a bag by hand is too tedious an operation to be of any practical value.

The invention consists of .a tool which grasps simultaneously the eyes upon the ends of the wire-tie and by the mere pulling of the tool-handle serves to twist the wire ends together adjacent to the eyes, and can then be instantaneously detached from the wire eyes, leavin them in the desired position to be untw-isted.

T t o i of th cl s h g spi a spindle with a l-ia-ndle fitted to the same so that the sliding of the handle causes the spindle to revolve. These elements are old; but in the present case I have added a swivel knob at one endof the spindle and a pair of hooks at the opposite and projected laterally upon the same, or opposite sides, from a head at one end of the spindle and disposed at a suitable distance apart to engage the eyes upon the wire-tie and to leave them when twisted in a suitable position for untwisting. V

In the drawing, Figure 1 is a side elevation of the complete tool looking toward the ends of the hooks upon the head of the spindle and showing the handle and the knob in section; Fig. 2 shows the head of the spindle viewed from the sideof the hooks; Fig. 3 shows the tie looped, as around the neck of a bag, and the eyes at the ends engaged with the hooks upon thetool; Fig. 4 shows a sec- Specification of Letters Patent. .ennaa n ma M m a 'Ser e .Nq-4a0.759-

6 shows the wire-tietwisted (as upon the bag neck) with the eyes spread apart; and F 1g. 7 shows the application of the tie and the tool to the neck of the bag.

The tool is formed with a spindle'having a cylindrical body a and a spiral body b with handle 0 fitted at one endto the cylindrical body and at the opposite end tothe spiral body so as to twist the spindle when slid over'the spiral body. A head d is shown upon the end of the body owith two books 6 and f projected at equal .distanees from the center line of the spindle upon the same 7 side of the head and at a suitable distance 'apart to engage the eyes 9' upon theiends of the wire-tie h, as shown Fig. 3, and to le e he am in re dines or u is ing h n t ey a 't is e s sh n in Fig. 6 .At the bases of the hook t he d .i hollowed out beyond the axial line of the spindle, and the hooks are therefore projected across such axial lineand are then recurved, as shown in Fig. 2, to form a secure engagement with the eyes upon the wire-tie. This con t tion for e h k gives e h o t em upon the inner sid a ho lo 0. ec s pon the en er l ne of th pi l so t the ire hen t is ed i a ly n lin w t th ax s at the p n Th p o uc a e y sm o h movement in twisting the wires and avpids any needless resistance. The spindle is pro.-

Y ded th a swi el d kn fitted to t rn pon the and oppo e h d n pull he spindle longitudinally through the handle 9 until the head is close to the handle, as shown .Fig-

In using the tool, one of the eyes 9 upon the wire-tie is engaged with the hook e; the wire-tie is then looped around the neck of the bag is, crossed over the portion on the hook e, and the other eye engaged with the hook f. This can be done with great facility by tipping the hag-neck a little sidewise as shown in F ig, '7, and the instant that the second eye is engaged with the second hook the handle 0 is pulled outwardly, and the spindle turns the head d with both the hooks, and twists the wire several times, as shown in Fig. 6. The crossing of the wire when applying the eyes to the hooks greatly reduces the fo rce required in twisting the wire.

It will be noticed that the hooks are recurved toward the head d so that as the head rotates there is no tendency for the eyes 9 to slip oti of the hooks, especially as the wire is under tension owing tothe pulling of the tool; but such recurved form permits the hooks to be instantly disengaged from the eyes when the tie is twisted, by pushing the tool slightly toward the bag neck. The hooks leave'the eyes separated as shown in Fig. 6, in the most favorable position for untwisting when it is desired to open the bag.

and grasping the knob with the other and pulling the spindle-through the handle. Without such knob, the handle could not be readily returned, as the spindle cannot be easily pushed through the handle, by reason ot-the hooks upon the head, which turns when the spindle is pushed from that end.

The tool is designed with special reference to taking it apart for cleaning, when grit or dust penetrates to the working surfaces, as

the tool is especially designed and adapted for use in cement mills, flour mills, and'anah ogous places, where it is greatly, exposed to grit and dust. Thecleaning of the tool is facilitated by the following construction:

The swivel-knob 2' is mounted upon a pin Z integral with the spiral'body bot the spindle, and is held detachably thereon by a screw m, as shown in Fig. 4, and the entire .of the spindle is removable from the F handle when the-knob is detached, as the spiral body I) can then be withdrawn from its nut and the interior of the handle readily wi ed out as well as the ortions of the spindle. This construction is of great value 40 and importance, as it permits the continued use of the tool in places Where it would'be entirely disabledunless it could be readily cleansed; The construction of the books 6 and f is also peculiarly adapted to the twisting of such wire-ties upon me neck of a bag or analogous situation, as the recurved points of the hooks retain the eyes of the wire-ties securely, when the handle 'is'pulled to twist the wire, but permit the instantaneous'disen gagement of the hooks from theeyes when the tool is pushed slightly-inthe opposite direction. It is'preferable that the two recurved hooks should. be substantially equidistant from the axis of the spindle, as'shown 5' infFig. 3., so that the tension upon the two endsof the wire tie may be equal and both hooks may operate equally in forming the twist which locks the wires together adjacent to the eyes, as shown in Fig. 6.

I find in practice that it is preferable to project the hooks e and f from the same side i of the head (Z; but as the twisting movement of the spindle is always in the same direction, it is obvious thatvhooks may be projected from opposite sides of the head and both projected forward in the direction of the mo vement, so as to retain the wire-eyes I 9 upon the hooks while twisting, and permit their immediate disengagementb'y turning 1 the spindle slightly to twist the-hooks out of ithe eyes. I Having thus set forth the nature of the invention what is claimed herein is:

wire ties having eyes upon their opposite ends, consistlng of the spindle a ha ing the tate the spiral body by a longitudinal movement, the end of the'spindlehaving two recurved hooks e and f equi-distant from the axis of the spindle and at a suitable distance apart to twist the ends of the wire tie and leave the eyes in position for untwisting. Y

2. The tool for twisting'wire-ties, consisting of the, spindle having the"cy lindrioal body a and the spiral body b with a handle 0 fitted to'both bodies, and the head (5 upon one end of the spindle with two hooks e'and fextended in the same direction laterally upon the head, equi-distant from the axis of the spindle and at a suitable distance apart to hold the ends of a wire-tie inposition for untwisting.

ing. of the spindle having the cylindrical body a and the spiral body bwith a handle a fitted to both bodies, thehead-d upon the endof the cylindrical body awith two hooks e and 7' extended in the same direction laterally upon the head equidistant from theaxis of the spindle at a suitable distance apart to hold the ends of a' wire-tie inposition for untwisting, and the knob 2' swiveled upon the end of the spiral body I) for drawing the spindle lengthwise in the handle.
